Xenogender is a both a standalone gender term and a family of MOGAI genders which encompasses all genders that “cannot be contained by human understandings of gender; more concerned with crafting other methods of gender categorization and hierarchy such as those relating to animals, plants, or other creatures/things.”
Most MOGAI genders fall under this incredibly broad (and infuriating) umbrella. In practice, however, the genders most often associated with the term have a space aesthetic (more cutesy/mythological than scientific) or an alien aesthetic. This being the case, all genders listed in the following section are a mess of saccharine space cuteness, poorly-understood Classical mythology, and pastel-colored-alien nonsense.

History of the term

Xenogender was coined was coined on June 24, 2014 by a since-deactivated tumblr user with the handle "Baaphomett," an individual also responsible for coining a number of other MOGAI terms. It was submitted to and posted on Mogai-Archive, the first real archive of MOGAI terms, making it one of the original generation of MOGAI terms.2

MOGAI-Watch Poem

Xenogender

Though I am a person,
my gender can’t be contained
by the gender binary
or within the human brain
(even though all the concepts
included in that list
are things that humans understand
and that they know exist.)

These influences can change how you label your gender, you may use masculine gender labels but still feel that your gender in + of itself is not entirely or much masculine at all.
The masculinity felt and shown is powerful and overwhelming and effects how you present and behave. The intensity is that of the sun.
This gender is heavily connected to the sun because of the preceived masculinity of the sun and the intensity of which masculinity can be felt by some people, that being why the sun alchemical symbol is present on the flag, the blue represents the sky and Masculinity, the orange represents the sun and the intensity of it. The white is for nonbinariness, nullgendered-ness or third-genderedness.

Sub-Categories Falling under the Xenogender Heading

Aesthetigenders

Aesthetigender is a subgroup of xenogender made up of all “genders” which are aesthetic in nature. While most MOGAI genders could (rightly) be said to fall under this category, this section (and the subsections following) are made up of MOGAI genders and categories which are the most blatant offenders.

Colorgenders

Colorgender is a subgroup of Aesthetigender which gives genders the properties of a color, either specifically or generally. It’s like they took the concept of having a favorite color and super-sized it, only twisted. And sad.

Gastrogenders

Gastrogender is a subgroup of aesthetigender which encompasses the properties of a flavor or type of food. You know, because that makes sense.

Though personalitygenders and esmogenders are not quite the same thing, they’re so closely-related that it made sense to group them together. Personagender is a subtype of aesthetigender wherein the gender takes on the emotional traits of a sentient being. Esmogender is a subtype of aesthetigender in which the gender causes the person identifying as said gender to feel specific emotions. Alternately, it is a gender which is felt under specific emotional circumstances. They are both pretty poor bases for a gender, and often seem to reflect the personality (or desired personality) of the person using the term. This is, somehow, a controversial thing to point out.

Relationship-Based Genders

Relationship-based genders are a subset of Personagender/Esmogender. These genders rely on one’s relationships with others to determine how, when, or if they manifest.
Textbook cases of lacking self-identity? You betcha.

Audiogenders

Audiogender is a subtype of aesthetigender defined by its connection to sounds or music. This is also patron gender category of that fourteen-year-old kid who likes to go on YouTube videos of early-70s psychedelic proto-prog-rock bands and complain that he was born in “the wrong generation” and that “there hasn’t been good new music since ’81, tops.”

Fictigenders

Fictigender is a subtype of Aesthetigender which is, unfortunately, exactly what it sounds like. Fictional characters (and trampled copyright law) abound. On the other hand, if you’ve ever wanted to turn your life into a bad fan-fiction of your favorite franchise, here’s your starting point.

Aedra/Daedragenders

Aedra/Daedragender is a subtype of Fictigender which is composed of genders derived aesthetically from the Aedra and Daedra of the Elder Scrolls universe. These beings are divine and/or demonic, and, regardless of their spheres of influence, have far better things to do with their godly powers than being patrons of MOGAI genders. There are nerds, and then there are nerds.
And then there’s this.

Exemgenders

Exemgender is a subgroup of Fictigender in which genders are based upon different types of Pokemon (poison, flying, fighting, etc). These are made even more ridiculous because the coiner of all 19 terms (thought here are only 18 types of Pokemon) decided to use Google to translate each type into Latin to make the genders sound more “official.”
Skye, we get it. You like the poke-bugs. Stop telling your mother she’s an oppressive tool of the cisheteropatriarchy because she won’t let you play your gameboy at the table and eat your carrots.

Naturogenders

Naturogender is subtype of Aesthetigender containing genders which are tied to nature in some way. Which is funny, because nature is a stone-cold bitch, and none of this MOGAI nonsense came from there.

Faunagenders

Faunagender is a subtype of Naturogender which encompasses all genders that are tied to (or influenced) by animals, brought to you by the coalition of (Former) Girls Who Liked Horses Too Much In Middle School and (Former) Girls Who Liked Cats Too Much In Middle School.

Floragender

Floragender is a subtype of Naturogender which encompasses all genders that are tied to (or influenced) by plants, in both a stoner and a non-stoner way.

Aerogenders

Aerogender is a subtype of Naturogender. This subtype encompasses all genders that change based upon surroundings, environment, or weather, because of course that’s a fucking thing MOGAI thinks human beings have happen to them.

Religiogenders

Religiogender is a subtype of Aesthetigender. This subtype encompasses all genders that have ties to religion (Judeo-Christian or otherwise). You can say a lot of things about MOGAI, but they sure do know how to skim the works of a lot of major religions! I think we have representatives from all of them (minus Islam).

Kingenders

Kingender is a subtype of Religiogender. Kingender encompasses all genders that are influenced by otherkinism. Because that one kid with a tail who got a demerit for growling at a teacher needed another thing going against him.

Mythologenders

Mythologender is a subtype of Religiogender. Mythologender encompasses all genders that are influenced by mythology. These multi-purpouse, bespoke genders are perfect for Renaissance festivals, nature retreats, or tripping balls on peyote in your friend Bo’s basement.

Zodiacgenders

Zodiacgender is a subtype of Mythologender. Zodiacgender encompasses all genders that are influenced by astrology. Unsurprisingly, these pseudoscience-y labels are all the rage among a pseudoscientific movement.

Sciencegenders

Sciencegender is a subtype of Aesthetigender. Sciencegender encompasses all genders that are aesthetically linked to scientific concepts. The irony is just…indescribable.

Mathgenders

Mathgender is a subtype of Sciencegender. Mathgender encompasses all genders that are aesthetically linked to mathematical or numerical concepts. Math was always a nightmare for me, and I can’t decide if having someone like this in my class would have made it more or less so. It would certainly have been more memorable.

Technogenders

Technogender is a subtype of Sciencegender. Technogender encompasses all genders that are aesthetically linked to technology.
Or, as those of us with genders linked to sports call them, nerds.
